Третий вход каждого элемента И 8-1 - 8-и соединен с выходом формировател 10 импульсов, вход которого св зан с выходом элемента ИЛИ 7, а выход каждого элемента И 8-1 - 8- и подключен, к второму входу соответствующего перек:-|ючател 3-1 - 3- И.З-вход каждого триггера 9-1 - 9- и соединен с соответ ствующей шиной 1-1 и 1-п управлени а R -вход каждого триггера 9-1 9-v - с соответствующей шиной 2-1 2-п .The device for remote switching includes buses 1-1 and 1-st and 2-, 1 -2-P control, connected respectively to the first and second inputs of switches 3-1 and 3 P, with opening contacts 4-1 4-P, elements NOT 5-1 - 5-h, the inputs of which are connected via disconnecting contacts 4-1 - 4-n switches 31 - 3-h with power supply bus 6. The outputs of each element NOT 5-1 - 5 are connected to the inputs of the element OR 7 and to the first input of the corresponding element AND 8-1 - 8-p, the second input of each of which is connected to the inverse output of the corresponding R 5 trigger 9-1 - 9-P.

Устройство дл дистанционного включени работает следующим образомThe device for remote inclusion works as follows.

При подаче управл ющих сигналов по шинам 2-1 - 2- и размыкающие контакты 4-1 - 4- всех переключателей 3-1 -3-и установ тс в исходное (замкнутое ) положение,а RS -триггеры 9-1 -9- п-в нулевое состо ние.Сигналы на выходах элементов НЕ 5-1 -5-п, а следовательно, на входах элемента ИЛИ 7 i на первых входах элементов И 8-1 - 8-h соответствуют уровню логического О. Сигналы на вторых входах элементов -И 8-1 - 8-h , соединенных с инверсными выходами соответствующих R5 -триггеров 9-1 9- h соответствуют уровню логической 1. Уровень сигналов на третьих входах элементов И 8-1 - 8-h соответствует логическому О, так как на выходе элемента ИЛИ 7 и соответственно на входе формировател 10 импульсов сигнал отсутствует. В результате такой комбинации сигналов на входах элементов И 8-1 - 8-П уровень сигналов на их выходах соответствует логическому О.When control signals are applied to the buses 2-1 - 2- and the opening contacts 4-1 - 4- all switches 3-1 -3-and are set to the initial (closed) position, and RS-triggers 9-1 -9- n-to zero state. The signals at the outputs of the elements are NOT 5-1 -5-n, and therefore, at the inputs of the element OR 7 i at the first inputs of the elements AND 8-1 - 8-h correspond to the level of logic O. Signals at the second inputs elements -I 8-1 - 8-h, connected to the inverse outputs of the corresponding R5-triggers 9-1 9-h correspond to the level of logic 1. The level of the signals at the third inputs of the elements And 8-1-8-h respectively corresponds to the logical O, since the signal of the output of the element OR 7 and, respectively, at the input of the imaging unit 10 pulses is no signal. As a result of this combination of signals at the inputs of the elements And 8-1 - 8-P the level of the signals at their outputs corresponds to the logical O.

Claims

When a device is exposed to vibrations or significant magnetic interference, it is possible for one or several break contacts 4-1 to 4-- n to go to the open position without passing through the buses 1-1 to 1-P of the control signal. In this case, the inputs of the corresponding elements are NOT 5-1 - 5-p and are disconnected from the bus 6 of the power source, and at their outputs, at the first inputs of the corresponding elements AND 8-1 - 8-h and at the corresponding inputs OR 7, the logical signals 1. At the output of OR 7, the signal of logical 1 will also be sent to the input} K) of the distributor 10, which will form an impulse h and give it to the third input of all elements AND 8-1 - 8-h. However, the pulses in the vehicle at the outputs of only those of the elements And 8-1 - 8-p, on the first and second inputs of KOTOPF.IX there is a signal of logical 1, i.e. at the outputs of those elements where contacts 4-1 are open - 4-p. The pulses also go to the second inputs of the corresponding switches 3-1 3- and transfer all falsely tripping break contacts to the closed position. When the control signal is fed through one of the buses 1-1 - 1 - and the corresponding R5 triggers 9-1 - 9 work, and the switch 3-1 3-p. Since the response time of the switch and opening of the corresponding contact 4-1 is A and longer than the response time of the RS trigger, the latter switches earlier both at its inverse output and at the input of the element associated with it. A logical O signal is generated. After opening the contact The included switch at the output of the corresponding element is NOT 5-1 - 5-n in turn with a signal of logical 1, as a result of which the driver 10 pulses will generate a pulse. However, this impulse will not pass to the output of the corresponding element AND 8-1 - 8-h, since the signal at its second input corresponds to a logical O. Thus, constant monitoring of the state of the contacts of the switches, which increases the reliability of the device, is due to prohibiting the passage of a pulse from the forcing unit to the second input of the switch when a control signal is applied to the last one, while in the absence of a 03 "triggering sigiapl pulse iic:) CTyii 4 is connected to the second inputs of those switches, contacts reopened due to vibration or significant magnetic interference on the device, claims Apparatus for remote switching on comprising remote switches, elements NOT based on the number of switches, element OR, pulse shaper, control buses, terminals for connecting a power source, the first and second inputs of each of remote switches are connected to one of the control buses, the input of each of the elements is NOT through the opening contact of the corresponding remote switch the switch is connected to the output for connecting the power source, the outputs of the elements are NOT connected to the inputs of the OR element, the output of which is connected to the input of the pulse shaper, which, in order to increase the reliability of operation, is introduced into it by the number of remote switches R5 triggers and elements And, the inputs of each of the flip-flops are connected to the control buses of the corresponding remote switch, the first input of each of the elements AND is connected to the output of the corresponding element NOT, the second input is output of the corresponding flip-flop, the third inputs of all AND elements are combined and connected to the output of the pulse shaper, the output of each AND connected to a second input of the respective remote perektiochatel.
